About Me

I am a Ph.D candidate at Institute of Science Tokyo (Previous Tokyo Institute of Technology), where I am supervised by Prof. Konstantinos Slavakis and advised by Prof. Jun Sakuma. My research focused on intersection of quantum computing, machine learning and security.

I obtained my B.S. in physics from the University of California, San Diego and M.S. in Experiment Particle Physics from The Graduate University for Advanced Studies, SOKENDAI.

What Problem to Solve?

For the opinion on research, one could refer the page here.

“Nature isn’t classical, dammit, and if you want to make a simulation of nature, you’d better make it quantum mechanical.” –Richard Feynman

Recent Update

Keywords Topics: \(C = \{\text{Quantum Computing}\}\). If we define two events \(x=\text{research}\), \(y=\text{publication}\), \(c =\text{rand}(C)\), \(P(y|x+c) \approx P(X>\mu+3\sigma) = \int_{\mu+3\sigma}^{\inf} \frac{1}{\sqrt{2 \pi \sigma^2} } e^{-\frac{(x-\mu)^2}{2\sigma^2}} dx\) The path to a sound research is complicated, especially the one that convinces yourself, you have fully committed your soul and life into a work.

AI Security

The on-going work includes the attack on various fine-tuned and pretrained AI models, like Llama2-7B, Llama3.1-8B-Instruct, Qwen, DeepSeek and GPT family Model. Coming soon!

Quantum Machine Learning

Currently I am working on the quantum computing library called LogosQ written in Rust programming language. The official documentation is on the website including some tutorials link. Recently, I published research in newly developed feature extraction algorithm on graphs that could be applied with VQCs in limited
